I like this picture. Although the the subject is not very interesting, I like the different tones of blue. That said, there are some things to improve upon. The crop shows slightly too much sky, and the column at the bottom annoys me a bit. I would either crop it closer, or show a bit more of it. On the other hand, ending the diagonals to the corners of the picture also gives some impact, so maybe crop a tighter to the left and right too.
I do like the reflection of the cloud, but not the reflection of the wire(?) at the bottom. Also the little dab of birds poo in the lower left corner is distracting. I realise that there wasn't much you could do about that in a Basic Editing Challenge, though.
Good picture, but maybe increase the contrast and sat. a bit to show more tones of blue.
This would be a 10 for me if the bottom area where the column is were cropped out about where to the bottom tip of the large cloud. Maybe just try it to see how it looks. However, it's still a great photo !
nice except for the black spot in the lowest left hand corner window pane. great cloud reflection. I think it would have been better just to crop out everything from the black spot down.
